The iPhones 6s has 3D touch API for native apps. I was wondering if Apple has enabled 3D touch access from Javascript for a web app?
Just like we use standard touch events
element.addEventListener("touchstart", handleStart, false);
Safari 9 supports it on desktop. See Responding to Force Touch Events from JavaScript in Apple's WebKit DOM Programming Topics.
I can't find any documentation on using it from Safari 9 on iOS, though.
